FCA recalls 850,000+ gasoline vehicles due to problem with catalytic converters

Green Car Congress

MARCH 14, 2019

Fiat-Chrysler of America (FCA) will recall more than 850,000 gasoline-powered passenger cars and SUVs due to a problem with their catalytic converters. NO x emissions in California are the most important contributor to ambient ozone and a key contributor to fine particulate matter pollution (PM 2.5 2012: Q2 2019.
